PHYSICAL GEOGRAPHY WILLIAM MARSH Describe an example of an open system and a closed system on Earth. For the open system, describe the specific energy and matter that comes into and/or out of the system. For the closed system, describe why energy and matter stays within the system. Using Figure 2.7 and Figure 2.16 in the textbook as a reference, describe any patterns you see on Earth that can be categorized based on latitude or longitude. In other words, look...

Question 1 - Analogue Closed Loop Control Systems Many control systems involve processing analogue signals such as heat, light and movement Therefore analogue closed loop control system require walogue processing devices such as the operational amplifier (op-amp). One of the most common control applications involves using the op-amp as a comparator. In it's simplest form a comparator just compares two voltage signals, VI and V2. Ir VI is higher than V2 the output, Ve, is 'low', VI is lower than...

A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....

Case 27 To Use or Not to Use?
Beaufort Sea Production Company (BSPC) operates a medium-sized oil
field on Alaska’s north coast. The field is still producing at its
maximum rate, 325,000 barrels of oil per day (BOPD). However, to
sustain this rate the company started a waterflood of the reservoir
two years ago. Now a capacity bottleneck in the water disposal
process is threatening to curtail production. In waterflooding,
salt water from the Beaufort Sea is treated to remove...
